Ampac System Line Terminator Installation guide

  • Hello! I've reviewed the Ampac Line Terminator 2980-0005 Installation Guide. This document details how to connect the Line Terminator to solenoids and Metrons, specifying resistance requirements and output capabilities. I am ready to address any questions you might have about the wiring configurations for this device.
  • What is the maximum number of solenoids that can be connected?
    What is the minimum resistance required for a single solenoid connection?
    What is the minimum resistance required for two solenoids?
    What is the maximum duration when extinguishant output is supplying 1A?
    What is the maximum duration when extinguishant output is supplying 3A?

GasRelease System Line Terminator
Installation Guide
Item Number: 2980-0005
Introduction
The Line Terminator facilitates the straightforward termination of the GasRelease Panel’s extinguishant output to a
maximum of two solenoids (described below) or multiple Metrons (see overleaf)..
Typical Solenoid Wiring
The GasRelease Panel’s extinguishant output is capable of supplying 1A
for a maximum duration of 5 minutes (the actual duration can be set using
the panel’s commissioning menus). If connecting one solenoid (as shown
in Figure 1), it must have a resistance greater than 30 ohms. If connecting
two solenoids (as shown in Fig. 2), each solenoid must have a resistance
greater than 60 ohms. Note that one Line terminator is required per
solenoid (max. 2 per system) and the quantity used (1 or 2) should be
programmed into the GasRelease panel via its commissioning menus.

Item Number: 2980-0005
Typical Metron (Igniting Actuator) Wiring
The GasRelease Panel’s extinguishant output is capable of supplying 3A
for 50 milliseconds to ignite one or more Metron-type actuators. If
connecting one Metron, wire as shown in Fig. 3. If connecting multiple
Metrons, wire the first to the Line Terminator’s solenoid/metron output and
all others in series with the extinguishant output’s +Ve line, as shown in
Fig. 4. Note that the total series resistance of the Metron(s) and wiring
should not exceed 7 ohms.
